To all whom it may-concem: I

Be it known that I, Joim H. Q'r'ruN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Shock-Absorbers, of which the following is a s ecification.

This invention re ates to a shock absorber or cushioning device which is more particularly designed for reventin shock or jouncing of automobiles or ot er vehicles when running over an uneven road but which may also be used for other purriises in which like conditions exist.

The object of this invention is to produce a device of this character which is comparatively simple and durable in construction, eilicient in operation and capable of being readily applied to automobiles or similar vehicles.

In the accom anying drawings consisting of two sheets: igure 1 is a side elevation of my improved shock absorber showing the same a pied to the axle and frame of an automo ile. Fi 2 is a top plan view thereof. Figs. 8 an 4 are vertical transverse sections in line 83, Fig. 1, looking in opposits directions. Fig. 5 is a horizontal section taken in line 55, Fig. 3.

Similar letters of reference indicate corresponding parts throughout the several views.

Although my improved shock absorber may be variously applied to an automobile the same is represented in the dr'awin as interpmed Mtween the axle A and the rame B of an automobile which parts are movable relatively to one another.

The preferred embodiment of my improved shock absorber is showmin the draw- 1 and is constructed as follows:

represents a bracket secured to the underside of the side bar or other art B of the automobile frame and provi ed at one end with an abutment D ha\'in an upright bearing face (I on its front side which is preferably curved inwardly.

t", represents a vertical rocking member which is preferuhl constructed in the form of u s gnwnt un provided with an outwnrtllv curved face e which enga es with the curved face of the abutment. he rocking member is yieldingly held by a tension derice in its eentrul or normal position in which the central part of its curved face engages with the abutment so that. any tendency to roll or rock said segment either upwardly or downwardly out of its central or normal position will be restrained or resisted. lhe preferred means for this purpose consists of a horizontal tension rod F arranged in an upright slot f in the abutment extending from the front side or face to the back side thereof, and also arranged at its front end in an opening f in the central part of the rocking segment, a horizontal Fin 9 extending transversely thro h the rec ing segment adjacent to the centre part of its curved front face and pivotally eonnccting the front end of the tension rod with the segment, a coil spring H surroundin the tension rod and bearing at its front en against the rear side of the abutment, a collar h arranged on the rear end of the tension rod and bearing against the rear end of the s rin and screw nuts 1' arranged on the t rea ed rear end of the tension rod and eng ing with the rear side of the collar. At its outer end preferably horizontally in line with the central part of the face of the segment the same is pivotally connected by a horizontal bolt j or otherwise with the 11 per ends of a pair of shifting links J w ich latter are 0 connected at their lower ends wi the a A so that when the latter and the frame move one relative] to the other out of their normal position, e segment will be rocked either up or down out of its central position on the abutment. Either of these movements of the segment causes the tension rod to be pulled forward and the a ring to be compressed and the strain on t 0 same increased. This strain on the spring increases in proportion to the extent'to which the segment is rocked either upwardly or downwardlyby the approach of the axle and frame or the separation thereof out of their normal or central position, owing to the increase in the leverage of thesegment toward either of its heels. This increased leverage not only increases the tension on the 8 ring but also enables the latter to offer gra ually incrensin resistance to the rocking move ment of t 1 se ment out of its normal centrul )OSlliOIl, waereby the cushioning or absorbing efl'ect of this device is automatically adapted tojthe shock or load which moves v the axle and frame out of the normal position, the cushionin efl'cct bein small when only a slight de ection of t e axle and rativel Gil l l I having a bearing face adapted to be connected name out of the normal occurs and propertionately greater as this deflection increases.

F r the purpose of preventing slippage ot' lllt segment on the abutment and insuring a rocking-movement of the same, the opposing faces of the segment and abutment are provided with cooperating interlocking means which preferably consists of a row of teeth k arranged on the face of the segment and a corresponding row of recesses k on the face of the abutment adapted to receive said teeth.

At its lower end the links J are preferably adjustabl; connected with the axle, so as to permit 0 adapting the shock absorber to the load to be carriednnd also to adapt the same to automobiles in which the distance between the axle and frame varies. The preferred means for this purpose which are shown in the drawings consist of a bracket L which is formed on the upper side 0! a clip plate I secured b its clip 0 to the axle and which is provide on one side with an annular row of teeth m, an adjusting arm N pivotally connected at one end by a. bolt n with the lower ends of the shifting links and rovided at its opposite end with an annulii'r row of teeth 0 which interlock with the teeth of said bracket, and a clamping bolt p connecting said bracket and ad usting arm and arranged centrally within the rows of teeth thereof. -U )0!) interlocking the teeth of the bracket wit the teeth of the am after the latter has been-adjusted to the desired position and then tightening the bolt p the parts will be held in their relatively adjusted position to suit the distance between the axle and frame or the normal load which is carried.
